Description

Technical Field

[0001] This utility model relates to the technical field of track adjustment devices, specifically a track adjustment device for a tracked transport vehicle. Background Technology

[0002] A tracked transporter is a transport vehicle that uses tracks as its running gear. A tracked transporter is a "vehicle" that uses a tracked running system instead of a wheeled running system. This type of vehicle has low ground pressure, minimal sinking, strong traction, and high mobility. Tracked transporters typically include a cab, a cargo platform or cargo box, and a tracked running system. The tracks are flexible links driven by the drive sprocket and surrounding the drive sprocket, road wheels, idler wheels, and track rollers.

[0003] In the prior art, the front end of the track of a tracked transport vehicle is raised to improve its climbing ability. However, when the tracked transport vehicle encounters a continuous uphill climb, the front end of the vehicle is raised, causing the track to be unable to contact the ground, reducing friction and making it easy to slip. To address this, a track adjustment device for a tracked transport vehicle is proposed. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a track adjustment device for a tracked transport vehicle, which has the following advantages:

[0019] This invention controls the second fixed frame and the second adjusting wheel to move downwards via a third electro-hydraulic push rod, while a first electro-hydraulic push rod controls the first side block to move the second support wheel toward the power compartment. This allows the track, pushed by the second adjusting wheel, to be subjected to a downward force, increasing the friction between the track and the slope, thereby improving the climbing ability of the tracked transport vehicle.

[0027] A second side block 15 is provided at the end of the power compartment 1 that is away from the first electro-hydraulic push rod 6. A third electro-hydraulic push rod 16 is installed at an angle on one side of the lower end of the second side block 15. A second fixed frame 17 is installed at the lower end of the third electro-hydraulic push rod 16. A second adjusting wheel 18 is rotatably installed at the lower end of the second fixed frame 17.

[0028] A third bracket 19 is installed at one end of the power compartment 1 near the second side block 15, and a third support roller 20 is rotatably installed at the upper end of the third bracket 19.

[0029] The drive wheel 4, the second support roller 9, the first support roller 3 and the third support roller 20 are provided with tracks 5, and the tracks 5 are connected to the drive wheel 4 in a transmission manner.

[0030] Please see Figure 1 , Figure 2 and Figure 3A side frame 13 is provided on the outside of the power compartment 1 near the second side block 15, and the side frame 13 is connected to the power compartment 1. The side frame 13 is used to install the camera 14.

[0031] Please see Figure 1 , Figure 2 and Figure 3 A camera 14 is installed on the outer side of the side frame 13 and is connected to the side frame 13. The camera 14 is used to observe the road conditions in real time.

[0032] Please see Figure 1 and Figure 3 The lower end of the first side block 7 is provided with a second electro-hydraulic push rod 10, and the second electro-hydraulic push rod 10 is connected to the first side block 7. The second electro-hydraulic push rod 10 is used to control the movement of the first fixed frame 11.

[0033] Please see Figure 1 and Figure 3 The lower end of the second electro-hydraulic push rod 10 is provided with a first fixing frame 11, and the first fixing frame 11 is connected to the second electro-hydraulic push rod 10.

[0034] Please see Figure 1 and Figure 3 The lower end of the first fixed frame 11 is provided with a first adjusting wheel 12, and the first adjusting wheel 12 is rotatably connected to the first fixed frame 11. The first adjusting wheel 12 is used to adjust the deformation of the track 5.

[0035] This solution: When encountering a continuous slope or incline that causes slippage, the first electro-hydraulic push rod 6 is retracted, while the third electro-hydraulic push rod 16 is extended. The second adjusting wheel 18 causes the lower part of the forward end of the track 5 to generate a downward force. The track 5 on the side away from the forward end tightens as the first electro-hydraulic push rod 6 retracts. The downward force generated at the forward end of the track 5 increases friction. At the same time, the camera 14 allows for real-time observation of the road conditions, and the track 5 is adjusted accordingly. The second electro-hydraulic push rod 10 is controlled to cause the first fixed frame 11 to drive the first adjusting wheel 12 downward, thereby causing the side of the track 5 away from the forward end to lift up, shifting the center of gravity forward, increasing the contact pressure between the front end of the track 5 and the slope, and further increasing the friction between the track 5 and the slope.
